Moxie Software has released Engage+,"the first social chat app that leverages Facebook’s social graph leveraging public profiles to target social visitors with unique proactive offers and provide agents with a rich set of social data." Until now, sales and customer service reps had access to limited customer data when interacting with customers via chat (e.g. customer name, purchase history, email, perhaps a few other data points). Engage+ utilizes Facebook's social graph to further understand and engage customers during chat conversations (e.g. age, brand likes, friends, mobile usage, and many more data points).
